我可以使用rufus-scheduler在rails中调度控制器方法吗? [英] Can I schedule controller methods in rails using rufus-scheduler?

问题描述

我可以从下面发布的控制器中安排索引方法吗?如果是这样，我将如何去做?

Could I schedule the index method from the controller posted below? If so, how would I go about doing that?

class WelcomeController < ApplicationController
  def index
   if Number.find(1)
    @number = Number.first
    @number.value += 1
    @number.save
   else 
    @number = Number.new    
    @number.value = 0
   end
  end
end

推荐答案

所以您似乎拥有一个Number模型.第一步是将逻辑从控制器转移到模型:

So you seem to have a Number model. The first step would be to move your logic from the controller to the model:

class Number

  def self.increment

    n = nil

    if Number.find(1)
      n = Number.first
      n.value += 1
      n.save
    else
      n = Number.new
      n.value = 0
    end

    n
  end
end

您的控制器随即成为

class WelcomeController < ApplicationController

  def index

    @number = Number.increment
  end
end

然后，也可以从调度程序中调用此增量"类方法.像这样:

Then this "increment" class method can be called from the scheduler too. Like in:

# file:
# config/initializers/scheduler.rb

require 'rufus-scheduler'

# Let's use the rufus-scheduler singleton
#
s = Rufus::Scheduler.singleton


# Stupid recurrent task...
#
s.every '10m' do

  Number.increment
end
